Lothario Gerard Butler is trying to woo gorgeous Kazakhstani billionaire Goga Ashkenazi. The Scottish actor, linked last year to Jennifer Aniston, has been in regular contact with the London-based beauty, a close friend of Prince Andrew, after they met at the Cannes Film Festival last month. And he was spotted visiting her West London mansion last weekend. A source told us, “Gerard was spotted chatting up Goga at a party in Cannes and they exchanged numbers.” An Oxford graduate with a gold-mining and construction company, Ashkenazi isn’t short of admirers. She once dated Italian Formula 1 boss Flavio Briatore and recently ended a relationship with Kazakh oil billionaire Timur Kulibayev, who is still married to Kazakhstani President Nursultan Nazarbayev‘s daughter, Dinara. Butler’s rep didn’t get back to us and Ashkenazi could not be reached.
